' OIL TANK.

Application le May 29,

To .'zlZb whom it 'may concern.'

die it known that I, JOHN A. Wem, a citizen of the United States, residing at Tulsa, inthe county of Tulsa and State of 'sealed at all times, to prevent escape of t e volatile contents contained in the crude oil,

while readily permitting the inspection of the flou" from time to time toI ascertain I' whether the pump is Workingproperly, and to determine the volume of flow therefrom;

The principles of the invention and the speciic construction, by means of which they are embodied, will be-more fully undern stood from ion taken in connection with the accomnanying drawings which illustrate the preilerred form of the invention.

In the drawings: Figure 1 is a vertical sectional View through an oil tank, with the invention applied thereto.

Figure 2 isa plan view ot the same with 'parts shown in section.

Figure 3 is a perspective view showing the relative arrangement of the inlet and outlet and other attachments.

The body 5 of the tank is constructed in the usual manner -frorn sections of heavy gage metal, joined together in an air-tight manner over an interior frame-work, which is composed of angle irons 6 riveted together. Acomparatively large casing 7 preferably about 16 inches in diameter, is located centrally of the tank and securely held at the top and bottom by angle irons 8 and 8", re

spectively. This. casing protrudes a short distance above .the roof 9 of the tank, Where it Txs closed by a suitable removable cover 10- and extends to within three'feet of the bottorn. The connection with the roof is air tight. An outlet pipe 11 extends through one side of the tank, and its intake end 11* extends downwardly nearly to the bottern of the tank; while the normal oil level is indicated at 12. A vacuum line 13 also communicates with the interior of the tank though an opening 14 in the roof.

the following detailed descrip- .thus opening the valve in 4 the bo 1923. Serial No. 642,285.

A.- pipe line 15, usually about two inches in diameter, extends directly from thepunip to the tank. In accordance with-the .present invention this pipe line hastwoz'branches 1G and 17 one of which enters the 'uppcrend of the casing 7 at a point 18 justuabo'vev thcI roof 9, while the other branch'haspa'ftloivnturned end 19 extending through.:fan/open ing 2O in the roof 9, dischargingrdjircfctly into the tank but outside of the-:easing T.

'The-branches 16 and17 are -pronidediintermediatetheir ends with valve-bomes-Z-und 22 containing ball safety valvesileitlier. one of which may be held closed by-.-1the-.ball 23 F while the other remains-open. al

The tank is also provided ,in its-roeifvith apressure relief valve 25, andranign-'holc cover 26. It is to be understoodthnt a'll connections are provided with. theyiisual .packing to provide air-tight'jointasogjthat the oil is prevented from evaporatiigeand vthe volatile gases are reventcd-.froinescaping While the casing and tlieouftltf'tllffxs sealed bythe liquid which is in sidethl Normally, while the pumpsare, i p tion, the ball 23 remains over-fthe valve in box 21. Whenever it is desired,tn aseertain if the pu 'ps are working.ethcientlywnr -Lo determine t e character of the oihdischlarged thereby all that is necessary iste reinpve thc cover 10 and to shift the ball 23 .tothteiosition shown in dotted lines at Q4 the valve in the box 22 isclosed. inspection is completed, the ball,.,..i,is replaced in its former position to .per-init the oil to be discharged directly into thetank. The cover 10 .is then replaced on-.tlie .uppcr end of the casing 7. Y It is tobe noted, ,howover, that during the removal of; the cover 10, the volatile contents of the tank is prevented from escaping by reason of the liquid seal at the bottom of the casing.

Although the construction above described is particularly designed for use in connection with oil Wells and pumps, the invention, of course, is not limited to such use, but may be used in connection with any pipe line through which liquid is discharged. It Will also be understood that the specific construction herein describbed is merely illustrative, and that various modifications may be made therein within the scope of whatl is claimed without departing from the s irit of the invention or sacrificing any o its advantages.

- What is claimed is;

end, and a supply pipe having valve controlled branches leading into the Ibody of the tank and the casing respectively.

2. In a device ofthe character described, the combination of at'ank, a casing extending within the tank, an outlet pipe for the tank, the .inner ends of said casing and pipe I the combination of a tank. a casing extend`- rg'liquid either into the casingor into' the being normally sealed by the liquid within the tank, the upper end of said casing being outside of the tank and having an independently removable closure, and a'supply pipe having branches leading into the body of the tank and the casing respectively, and individual valves "for .controlling said branches.-

3. In-a device of the character described,

ing through the roof of the' tank and having its lower lend spaced from the bottom lthereof, an outlet pipe extending through the side wall of the tank. above the lower ndof the casing, a removable closure for 'the u per end o the casing, and a supply pipey aving means for optionally dischargy of the tank. 4. In a device of the character described, thecombination of a tank, a centrally disposed vertical casing extending through the roof thereof and provided at its upper end with a removable closure, an outlet pipe extending-through the side wall of the tank,

^` the inner end of said pipe and the lower end 40' of thecasing being spaced from the bottom of. the ,tank'but' below the normal level of the lliquid within, and a supply pipe having valve controlled branches leading into the of the tank and the casing respectively, sai casing being materially larger in diametejr than thesuppl pipe.

5. In a device of the character described,

, as my own,

the combine@ of a mk, a @muy iisposed vertical .casing' extending through the roof thereof and provided at its upper end with a removable closure, braces inside the tank rigidl 'supportin said cas' g at its upper and o wer ends, t e lower iid of the casln bein below` the normal level of the liqui insi e thetank, and a su ply pipe having one branch opening into'the casing above the roof, having' another branch extending through the roof into the interior of the tank butoutside the casing, and separate valves for inde endently controlling the dischargeof liqui through the respective branches. Y f

6. In andeviee of the character described, the `combination of a tank, a casing extendlng through the cover of the tank within the latter to a point above the bottom thereof, the lower end of the casing being open,

' means for' opening or closix-gthe upper c'nd of the casing outside the ta a Supply Pipe havin valve controlled branches leading into t e'tank and..casing respectively, and

an outlet pipefor the tank having its lnner end normally sealed by the liquid within the tank.

7. In 'a device of the character described, the combination of a tank, a centrally disL posed vertical .casing extending through the roof thereof and provided at its upper end with a removable closure, the lower end of the casing lbeing below the normal level of the liquid inside the tank, and a supply pipe having one branch opening into the casnig above the roof, having another branch extending throug'h the root'V into the interior ofthe tank but outside the casing, separate valve .boxes in each branch containing valves, and a removable ball `for the valves, whereby one of -the valves" may remain closed while the other is open, and :vice versa.'-

In testimon that I claim the foregoing have hereto aixed my signature.
